Watch out, it’s moving. The official specifications of PCIe 6.0 just dropped and the least we can say is that there are big changes, starting with a monstrous bandwidth of 256 GB/s (on a 16 lane connection), which is 4 times the bandwidth of PCIe 4.0 and 2 times the bandwidth of PCIe 5.0. In short, there is a margin, knowing that PCIe 4.0 is already reserved for the high-end components of our PCs (GPU, SSD, etc.).
As a reminder, the PCIe (Peripheral Component Interconnect Express) standard provides the connection between various peripherals/components and the Motherboard (CM)
The consortium behind these specifications explains that initially (which will last for some time), PCIe 6.0 will be reserved for the most advanced professional sectors of technology, such as the army or aerospace. Perhaps we will see the standard land in a future PS5 Pro or Xbox Series XX, but the fact remains that the general public is not yet concerned. The first devices embedding PCIe 6.0 should be available on the market within 1 year 1/2.
